Subtract the integers and subtract the fractions. When the fraction to be subtracted is bigger than the first fraction, change the mixed numbers to improper fractions first then do the subtraction.
Abstract: We consider energy-efficient multi-user hybrid downlink beamforming (BF) and power allocation under imperfect channel state information (CSI) and probabilistic outage constraints. In this ...
Abstract: Multiplying matrices can be very challenging although it seems straightforward. Many researchers have studied the multiplication of two $2 \times 2$ matrices by using the Strassen Algorithm ...
